A simple iOS app with a TextView and a button that clears it.

###Step 1: Create the ViewController

• Create a new file
  • TextViewController
  • Subclass of UIViewController
  • select “Also create XIB file”
• Import the class in the appdelegate, set the viewcontroller in a navigationcontroller as the rootviewcontroller of the window. (we’ve done this 10 times, you should have this down)

###Step 2: Add a TextView

• Add a textView property (IBOutlet) to the viewController
• Add a textView to the view in the XIB file
• Wire the textView to the viewController’s property
• Set the text of the textView in the viewDidLoad method to something clever.

###Step 3: Add a Button

• Add a buttonTapped:(id)sender method to the viewController
• In the buttonTapped: method, set the textView’s text to empty (@””)
• Add a button to the view in the XIB file (set the title to “Clear Me”)
• Wire the button’s touchUpInside to the buttonTapped: method
